Here's the ls -l output for 10 files over 6 days. I'm just interested in the timestamp in the filename, which doesn't correspond much if at all to the file modification date. So I guess I need to figure out some way of parsing out the date (ie, 2009-01-01) and the time (ie, 12-09-44-58) and comparing them - and I think I have examples of how to do that in other scripting languages (R & perl). But I'm still not sure how to go from the output of something like that back to telling the file system which actual file to copy to a different directory.

SYSTEMD-VOLATILE-ROOT.SERVICE(8)                           systemd-volatile-root.service                          SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME

       systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile

SYNOPSIS

       systemd-volatile-root.service

       /lib/systemd/systemd-volatile-root

DESCRIPTION

       systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
       original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
       /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
       enabling fully stateless systems.

       This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
       line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
       service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
